Move the decimal twice to the right to get a decimal (it should start behind the 2 and end up in front of the 7)
For a fraction just put it over 100 72/100
The value of x is
-4x + 8 = 42
-4x = 42 -8
-4x = 34
x = -8,5
Answer:x=3
Step-by-step explanation:
-5x=-15
divide by -5
x=3
First you need to find how much 20% of $18.50 is. To do this, you need to multiply 18.50 by 20% which in decimal form is 0.2
$18.50x0.2=$3.70
Now you need to subtract $3.70 from $18.50
$18.50-$3.70=$14.80
Now that you have the new price, you need to find 6.75% of it to get the sales tax, so you multiply $14.80 by 6.75%, which is 0.0675 as a decimal.
$14.80x0.0675=$0.999 or $1
Now you add the sales tax to $14.80
$14.80+$1=$15.80 or $14.80+$0.999=$15.799
